My reverb tank crapped out...where can I get a new one? Tried e-mailing Evans and haven't gotten a reply and the 800 number listed on the site didn't work.

| I had no luck either recently. I used a Peavey tank and it worked very well. |

Evans has not used spring reverb in about ten years. You can try, but I have a hunch you will not find it there.
I tried ever Accutronics distributor I use and they did not stock the tank. Accutronics has been bought by Belton and moved to Korea. I emailed Korea about it and they said they were still moving the machinery over and it would be a while before they could build it.
I went over this with Jim Evans and Derrell Stephens as well. The Peavey tank worked perfect, even though the input impedanace was a bit different. My amp was not a wall mount unit! That would require a different tank, as the Peavey is a horizontal mount tank. |

| IS it a bottom or side mount? You can get tanks at Antique Electronics that are for Peavey. What is the number on the old tank? |

The old Accutronics reverb tanks came in three types, types 4, 8, and 9, with various input and output impedances available to match different amp specs. Getting the correct impedance match is very important so a little research may be in order.
The type 4 is 17" long and has 2 long springs, each of which consists of two springs joined in the middle, thus classed as a 4-spring unit. This was the original unit chosen by Leo Fender.
The type 8 is 9" long with 3 springs, commonly used by Marshall.
The type 9 is 17" long and uses 3 long springs, each consisting of two springs joined in the middle. These units deliver a more dense and complex reverberated sound than the types 4 and 8. These are my favorite for steel and are found in the old Randall amps, among others.
The original Accutronics' part numbers, still in use by Antique Electronics (and by Belton, who recently purchased Sound Enhancements and the Accutronics name and have moved the manufacturing of these units to South Korea), consist of 7 characters as described below.
1st character: Basic Tank Type - 4, 8, or 9
2nd character: Input impedance @ 1kHz
Type 4:
A=8 ohms B=150 ohms C=200 ohms D=250 ohms E=600 ohms F=1475 ohms
Types 8 and 9:
A=10 ohms B=190 ohms C=240 ohms D=310 ohms E=800 ohms F=1925 ohms
3rd character: Output impedance @ 1 kHz
Type 4:
A=500 ohms B=2250 ohms C=10000 ohms
Types 8 and 9:
A=600 ohms B=2575 ohms C=12000 ohms
4th character: Decay time (same for all types)
1 = short (1.2 to 2 sec)
2 = medium (1.75 to 3.0 sec)
3 = long (2.75 to 4 sec)
5th character: Connector arrangement (same for all types)
A = input grounded, output grounded
B = input grounded, output insulated
C = input insulated, output grounded
D = input insulated, output insulated
6th character: Locking device (same for all types)
1 = no lock
7th character: Mounting plane (same for all types)
A = horizontal,open side up
B = horizontal, open side down
C = vertical wall,long axis horizontal, connectors up
D = vertical wall, long axis horizontal, connectors down
E = vertical wall, long axis vertical, input up
F = vertical wall, long axis vertical, output up
The following table summarizes the above data for the most commonly available units:
PART NUMBER / PRIMARY USER / LENGTH / NUMBER OF SPRINGS / INPUT IMPEDANCE@ 1KhZ(DC resistance) / OUTPUT IMPEDANCE @ 1KhZ(DC resistance)
4AB3C1B / Fender / 17" / 4 / 8ohms(.81ohms) / 2,250ohms(200ohms)
4BB2C1B / Acoustic/SLM/Ampeg / 17" / 4 / 150ohms(26ohms) / 2,250ohms(200ohms)
4EB2C1B / Peavey / 17" / 4 / 600ohms(58ohms) / 2,250ohms(200ohms)
4FB3D1B / Music Man, General / 17" / 4 / 1475ohms(200ohms) / 2,250ohms(200ohms)
9AB2C1B / Fender, Boogie / 17" / 6 / 10ohms(.81ohms) / 2575ohms(200ohms)
9EB2C1B / Peavey, General / 17" / 6 / 800(58ohms) / 2575ohms(200ohms)
9FB2A1C / General / 17" / 6 / 1,925(200ohms) / 2575ohms(200ohms)
8AB2A1B / Boogie / 9" / 3 10ohms(.81ohms) / 2575ohms(200ohms)
8BB2A1B / SLM 9" / 3 / 190ohms(26ohms) / 2575ohms(200ohms)
8DB2C1B / Marshall / 9" / 3 / 310ohms(36ohms) / 2575ohms(200ohms)
8EB2C1B / Fender / 9" / 3 / 800ohms(58ohms) / 2575ohms(200ohms)
TMI? Perhaps, but there you are. If you have the old tank you can check the part number printed on the cover against this chart to determine the impedances, etc.. If you simply want to replace the orignal unit, or if you want to change to a different decay time or spring configuration than what you already have you can figure out from the chart what the correct part number is.
As mentioned above, contact Antique Electronics and tell them what you need and chances are pretty good that you will have a replacement unit in hand very soon and usually for less than $45, freight included. If you want something that Antique Electronics does not have in stock you will have to order it from Belton in Korea - email 'belton2@daum.net' (US Rep) & 'belton@unitel.co.kr ' (South Korea factory) |

side mount...short 9" tank with 3 springs..there are two numbers stamped on it. 8FB2B1F and 40 188 98....not sure which is the part number.
Scott
PS: Just got this via e-mail from Scot Buffington:
pan style 3 spring Type 8 reverb - Part # 0008-FB2B1F-BUF. |

Dave, thanks for posting the actual resistance values. I have bugged Cal Shuett in the past to give me actual numbers from resistance values. I don't like the short (type 8 tanks), and have changed several amps to the type 4 with the same (medium) delay, and it sounds so much better to me. I used a type 9, long delay for my "Twin" build, and it sounds great with the Sho-Bud. You almost have to turn it off for 6 string. Thanks again for the information!

"8FB2B1F" is the model number, Scott, and by referrong to the above information we find that it signifies:
8 = Type 8 (9" long, 3 springs, commonly used by Marshall)
F = 1925 ohms input impedance @ 1kHz
B = 2575 ohms output impedance @ 1kHz
2 = medium (1.75 to 3.0 sec) decay
B = input grounded, output insulated
1 = no lock
F = vertical wall, long axis vertical, output up
Personally I'm with Bill 100% on this, the long decay type 9 is heaven for pedal steel guitar. In your case it would be model number 9FB2B1F if you have room to mount it on the side like the original, if not then refer to the data again to see which last digit is correct for your preferred mounting orientation. If you wanted to place it on the bottom of your amp, open side down, you would order model number "9FB2B1B" and most likely pay under $40 including shipping.
Other than changing to a favored speaker this is probably the most cost-effective amp upgrade you can make. |

I doubt you will find either tank for the amp mentioned above. I went thru that for about a week!
As close as I could get was the following, a long tank, 3 spring.
at tubesandmore.com
P-R9EB2C1B
Catalog Page 94
Reverb Tank - Medium Decay, Medium Tank, Insulated Input
800 ohm input, 2,575 ohm output, medium delay, insulated input, grounded output connectors, horizontal, open side down mounting.
Replacement for stock Peavey Classic series tanks.
Outer channels measure: 16.75" Length x 4.375" Width x 1.313" Height
RoHS Compliant |

| If you want to try Ken's idea, I've got a 8EB2C1B I recently pulled out of a Champ 25, and installed a 4 series unit. Send me your address, and make a donation to B0b if you want it. |

| Thanks for all the help folks! I think i may have found one that was taken out of an Evans amp. Hopefully this will solve the problem. |
